Top recommended Class A certified UV water filter system (pre-assembled!)
- One of the few fully NSF certified to NSF/ANSI Standard 55 Class A
- UV intensity monitor with diagnostics makes it easy to monitor performance
- The UV lamp has twice the output of current high-output lamps but the CoolTouch fan significantly reduces water temperature

The Viqua Pro10 UltraViolet (UV) Disinfection System is one of the most stylish of these types of water purification systems and one of the few fully NSF certified to NSF/ANSI Standard 55 Class A (for Flow Rates of 10 GPM). It comes pre-assembled, so is very easy to install, and its sleek stainless-steel finish might mean you regret it being hidden under the sink and find all manner of ways to show it off to guests.
The color-coded plug and play connections enable quick and simple set-up and a UV intensity monitor with diagnostics makes it easy to monitor performance. The UV lamp has twice the output of current high-output lamps but the CoolTouch fan significantly reduces water temperature, so you don’t waste water running the tap until water runs cool.
The Viqua Pro10 system produces about 10 gallons of purified water per minute, meaning it’s a little slower than some cheaper, less effective options. Realistically, though, 10 GPM is more than most home flow rates of 6 GPM, so it shouldn’t pose a problem. Indeed, this model is recommended for light commercial applications and other facilities with a higher demand for water as it offers twice the raw power of other UV systems. Viqua also offer a 20GPM option, the Viqua Pro20, and PRO10S, PRO20S, PRO30 and PRO30S are all also certified Class A.
This unit is fairly low maintenance, requiring an annual change of the UV lamp (depending on how often you use it), and three-monthly cleaning of the quartz sleeve. Replacement lamps are not overly costly, so this is a good option if you’re on a budget.
All in all, I wouldn’t recommend a UV system for home water filtration. They’re expensive, useless if there’s a power outage, and can be rather fiddly, especially as you have to first filter your water to remove sediment and, ideally, other contaminants such as VOCs and heavy metals. That said, if you’re keen to get a UV system, the VIQUA is highly recommended.
Viqua Pro10 vs. Pelican Water PUV-8 and Puv-16 vs. Viqua E4-V vs. Viqua SV8Q-PA
The Viqua Pro10 carries Class A certification, features the CoolTouch fan and other safety features and is best in class for UV water purifiers. That said, it is expensive and may be unnecessarily powerful if you are simply looking for backup for water already treated by your municipality. If that’s the case, the Viqua E4-V is a good option if you’re looking for a faster flow rate at a good price with Class B certification. Or, if Class B will do and you don’t need a higher flow rate, the Viqua SV8Q-PA is probably your best option. The Pelican Water PUV-16 offers a greater flow rate and Class B certification but is harder to track down and almost as expensive. All in all, if your water is untreated and has tested positive for microbial contamination, go for the Viqua Pro10 as part of a more comprehensive water filtration and purification system.
